CORN -SHOCKER.

SPECIFICATION forming part of Letters Patent N 0. 724,515, dated April 7, 1903.

Application filed February 20,1902. Serial No. 94,937. (No model.)

To all whom, it may concern: 7

Be itknown that I, JOSEPH M. SHIvELY, of Alfred, in the county ofDouglas aud-Stateof Kansas, have invented certain new and useful Improvements in Corn-Shockers, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a plan view of the improvements in the corn-shocker shown and described in the patent granted to me, No. 559,75l, dated May 5, 1896. Fig. 2 is particularly intended to show the framework and gearing. Fig. 3 is a perspective View as seen from the stubble side. 7 Fig. 4 is a bottom side view of the shock-forming table. Fig. 4: shows a shock on the table and construction and arrangement of the crane for lifting the shock therefrom. Fig. 5 is a perspective view showing the arrangement of the gearing and sprocketwheels for actuating the gathering devices. Fig. 6 is a detail of the crane and its support. Fig. 7 shows the means for securing the foot of the crane-post to the main frame. Figs. 8 and 9 are details of the turn-table of the lifting-crane. Fig. 10 is a sectional view showing the construction of the shock-lifting Windlass. Fig. 11 is a section on the line 11 11 of Fig. 10. Fig. 12 is a detail of the pin 0 a portion of the table, and a portion of the shock-forming core.

This application is devoted mainly to do tails of construction embodied in the machine made subsequent to the making of that shown in the patent referred to; but some of the salient features of the machine are embodied in other applications for improve ments in corn-shockers-namely, that executed by me January 13, 1902, and that executed by me January 16, 1902.

In the drawings, A is the stubble-side supporting-wheel, which serves as a prime mover for the various working parts of the machine. A is the grain-side supportingwheel. Upon these Wheels the frame is suitably mounted. As the direct means for supporting the frame upon them is old, it need not be described here. Suffice it to say that the frame is adjustable in height thereon.

the shock-forming standard.

surface of the said shook-forming table is se the casting c of harvesting-machines generally.

B is the rear sill of my machine. B is a bar connecting the finger-bar to the B is what may be termed the finger-bar rear sill at the grain end. B is a sill connecting the same parts near the middle of the frame, and B a similar bar connecting the same parts at the stubble end of the platform. I) and b are bars for maintaining the position of the sill B C is the shock-forming platform, provided upon its upper surface with the curved radial arms 0. Any means that will give the upper side of the said shock-forming platform a surface that will act aggressively on the butts of the stalks resting thereon and move them as positively as possible may be used, the preferred form being that shown and described, which is such that the ribs shall have the double function of acting upon the stalks to compel them to rotate with the table and also because of their radiallycurved form tend to move the butts toward To the under cured the large bevel-gear 0. (See Fig. 4.) Upon the center of the table and beneath I place the plate 0 and concentric with the axis of the wheel I form in it the groove 0 In the eye of the table is inserted the pin 0 The said pin is adapted to enter an eye in Concentric with the said eye is formed a groove in this casting, in which I place balls 0 for the purpose of reducing friction as much as possible.

Surrounding the main wheel A is the wheelframe B suitably secured to the platformframe. Behind the main wheel I place a transverse shaft a, in suitable bearings and uponit place the usual clutch and sprocketwheel a. Connected to the main wheel in the usual manner is the large sprocket-wheel (1 Around this and the sprocket-wheel a is thrown the chain a D is the cutting apparatus for severing the heads. It is moved through a pitman d, that is moved by the crank d upon the forward end of the shaft (Z supported in suitable bearings on the main frame. Upon the shaft a is the sprocket-wheel E, which is as one piece with the bevel-gear e, which through a IOC and supports the gathering-board H.

suitable pinion on the shaft d gives motion to the cutting apparatus.

f is a stationary pin suitably supported by the bar 19 and by the bar b of the wheelframe. Upon this revolves a sleeve, which consists of the sprocket-wheel F and the pinion f. When the table 0 is in position, the large gear upon its under side meshes with the pinion f, and it is thereby given rotation. As means for supporting the table at its periphery I provide antifriction-rollers g g and g and the pinionsf, g, and 9 all supported by suitable bearings. The pinions f, g, and g are shrouded up to their pitch-circles, as shown at g of the pinion g in Fig. 5, and the teeth of the gear 0 are provided with shrouding 0 as shown in Fig. 4. The surfaces of these shrouds, corresponding as they do with the pitch-circles of the gear and pinions,serve as antifriction-rollers over which the periphery of the table may move. serve another purpose, which will now be explained.

The devices for conducting the-standing corn to the cutting apparatus and shocking mechanism consist of the gatherers H and H. These are supported by the bars I and I. The bar I is secured to the bar B at its rear end and to the finger-bar B at b and extends forward and supports the gath'erer H. The bar I is secured to the cross-brace b and to the finger-bar B at 6 It extends forward The boards H and H may be supported at their rear ends in any suitable manner. To avoid confusion, the support is omitted. Suflice it to say that the brace 76, secured to the fingerbar B, forms a part of said support. Under the board in the gatherer H is the board h and upon it the chain having the teeth 77. This chain does not difier from the corresponding chain beneath the board in the gatherer H, which will soon be described, and

hence will be passed over for the present except to show the means for operating it. As one piece with the pinion 9 which is supported upon a pin passing through the braces b of the main frame, is the sprocket-wheel g Upon the board it by suitable lugs is secured the bearing h, within which revolves the shaft, upon the lower end of which is mounted the bevel-pinion h and upon the upper end the sprocket-wheel it. (See Fig. 1.) At

*the lower end of the board it is an idler,

around which the chain passes. Intermeshing with the bevel-pinion 72. is the bevel-pinion h", having as one piece with it the sprocketwheel h supported in the bearing h Around this sprocket-wheel and that g is thrown the chain It". As the table is rotated by the pinion f it gives rotation to the pinion g ,and through the sprocket-wheel, chain, and bevel-gearing the stiibble side gathering-chain isactuated.

The stubble-side gathering device is sustained laterally by the brace B The grain-side gathering devices are operated in a similar manner by gearing. (Shown in Fig. 5.) The pinion The pinions' g and the bevel-pinion'j revolve on a stationary pin suitably secured to the main frame. The pinion j meshes into that j upon the shaft 3' which is supported in suitable bearings secured to the framework, which, so far as the essentials of its support are concerned, consists of the post K,(see Fig. 3,) which by the braces k and k is properly stayed to the main frame.

.Footed in a suitable bearing on the bar I is the shaft L, which at its upper end is sustained in the bearing Z, secured to a forward and stubblewardextension on the post K, as seen in Figs. 2 and 3. Upon the shaft j are the sprocket-wheelsj andj. Upon the shaft L is the sprocket-wheel Z By means of the chain Z passingaround the sprocket-wheels j and 1*, the shaft L is given rotation. Upon the board h is placed the chain M, thrown around the sprocket-wheel m at its lower end and its upper end around the sprocket-wheel m. The sprocket-wheelj at its upper end is provided with a knuckle-like termination; but as this construction is in common use it needs no further description. Sufiice it to say thatit may be treated as any ordinary knucklejoint connection that will permit diagonal placement of the sprocket-wheel. Around the sprocket-wheel 7' and that m is the chain m The chains Z and "m are kept taut by suitable idlers, as shown in Fig. 5. Upon the shaft L are the gathering-reels N, N, and N 0 and O are shields provided with the slots 0 and 0, through which the fingers of the reels extend. P is a shield secured to the post K and adapted to lie over the reel N ard Q, and surrounding the table is the wall Q. Supported upon a post Q are the springs q q and q, and suitably supported on the main frame and reaching through a slot in the wall Q are the springs q and q. The table, wall, shock-forming standard, and springs forming the subject-matter of another application soon to be filed need not be here described.

R is the main post of the crane for lifting the shock from the shock-forming table. It consists of a strong pipe, which at its foot is halved to the sill B outside of and beside the main supporting-wheel. Suitably secured to the platform-frame and main wheel-frame at their lower ends are the braces R, R R and R At their upper ends they unite and bolt to lugs, as 0, formed on the casting 7'. Thus practically united at their upper ends and theirlower ends secured to the platform-frame at four places somewhat distant from each other theyform what may be considered a pyramid system of bracing the latter to resist torsion, for it will be readily understood that their lower ends being so distanced from each other and their upper ends united all stresses that would produce torsion of the platform, due to strains produced by a heavy shock or by the gathering devices striking the ground at their forward end, are resisted;

This system of bracing, which so well serves to prevent any twisting out of proper position of the parts of the platform-frame, is also made to sustain the crane. The casting r is provided with what-may be considered the tracks r and Upon the pipe R and adapted to revolve therearound is placed the casting S. This is providedwith the antifrictionrollers 8, (shown in Fig. 6 and in dotted lines in Fig. 8,) adapted to roll on the track r Within this casting S are also theantifrictionrollers 8', adapted to roll on the track T The rollers s and 8 may be considered merely as antifriction devices to render the turning of the crane upon its vertical axis easy. Upon the casting S are the lugs s and 3 having pivoted at s the boom of the lifting-crane. In the bearing r (see Fig. 9) is the crankshaft r having the screw r and the crank T Upon the periphery of the casting S is formed the toothed segment S, which when theparts are assembled, as shown in Fig. 6, meshes with the screw r. It will be understood that by turning the crank R the casting S will be rotated relative to the post and the casting which supports it. By this means the crane is swung to the rear when the shock has been lifted from the table.

Upon the braces R. and R is supported the bracket T, in which is journaled the crankshaft t. R is a brace connecting the casting S to the top of the post R, and R is a'brace extending from the casting C to the foot of the post B. These braces perform no function other than giving strength to certain parts and need not be dwelt upon. Upon the shaft t the drum U is loosely placed, so that. it may turn independent of the said shaft.

Upon the shaft is secured the ratchet t, and

upon the bracket T is pivoted the pawl t Around the drum is wound the rope 15 which passes up along the crane, over the sheaves, and downward to the shock, to which it is secured indirectly through the instrumentality of the shock-forming post. By the arrange ment shown and described the shock may be.

raised by turning the crank and held in suspension through the instrumentality of the pawl 25 The operator may then by turning the crank r cause the crane to swing rearwardly and by then setting the drum free permit the shock todrop to the ground. In order that the drum may be easily set free and turn when the shock is dropped, I connect it with the crank-shaft t, as shown in detail in Fig. 11. Secured firmly to the shaft is the immovable member of a clutch i At one end of the spool, outside of the V braced to the frame bythe bar V flange, a sleeve 25 is extended, having upon it the splines t and i The eye of the movable part 25 of the clutch is adapted to be placed on this sleeve and is compelled to turn therewith by the splines t and t In order to lock the movable part of the clutch to the fixed part, the spring t is provided, which surrounds the sleeve at the end of the drum U. Upon the bracket T is pivoted the forked lever 15 The operation of this device for raising the shock will be understood by reference to Figs. 1, 4n, and 11. The crank is turned until the shock is of sufficient height. The pawl 15 then sustains it. The shock is then swung to position for dropping, and the lever 15 which is crotched to engage a groove in the clutch, is moved, which sets the spool free and permits itto revolve Without carrying the crank with it, which it would do but forthis clutch.

The novelty in the gathering devices consists in the use of the gathering-reels upon vertical axes, in combination with inclined gathering-boards, chains, cutting apparatus, and shock-forming table.

V is the tongue, pivoted at v to the main frame, and V the tongue-brace, pivoted to the main frame at 1: Upon the forward portion of the main frame is erected a standard Upon this is pivoted the bell-crank '0 Connecting the said bell-crank to the tongue and pivoted thereto is the bar o. Mounted upon the main frame is the quadrant W, and pivoted to the same is the lever to, having a thumblatch at its upper end and a spring-catch adapted to engage the quadrant W. W is a rod connecting the said lever to the bellcrank. By the movement of the lever.W the position of the frame of the machine relative to the tongue may be changed at will. I y

X is an additional support adapted to be permitted to fall to the ground and sustain the rear part of the machine when the shock is swung to the rear. As this forms the subject-matter of another application it need not be described here. The chain 6 which connects the sprocket-wheel'E with that F,

is provided with the shoe-tightener 6 that may be adjustable and secured by the set-. v

screw a shown or'by any other means.

The value of the clutch on the Windlass lies to a large extent in setting the rope free withoutim parting motionto the crank, which would retard the dropping of the shock somewhat. By setting the rope free quickly the shock is permitted to strike the ground when moving rapidly, and thus the bottom of it conform to the ridged surfaces ofthe cornfield. Because of this the butts of allthe stalks rest upon the ground and the shock is rendered much more stable. p

Regardless of the tilt of the machine. while cutting I find it desirable to have the platform level when lifting the shock off; other-\ .wise the shock-forming post Qhas atendency to bind on thepin c, that sustains it in its erect position,'and,furthermore', if the machine is not level the shock has a tendency to swing like a pendulum after set free from the pin, which is likely to continue until dropped to the ground, thus permitting the shock to stand a little inclined because of the fact that the stalks upon the side that strikes first will be driven upward relative to the others. I find it preferable to have the parts of the gathering devices which move the stalks onto the stock-forming table move on vertical axes, and thus pass the stalks backward without a tendency to lift them. I'prefor to make the quadrangular frame that surrounds the wheel of two bars, or a single bar may be used instead sufficiently long to form the four sides.

What I claim as my invention, and desire to secure by Letters Patent, is
